tire size?

[iLOVEmyS13]

I have a set of Sportmax 006 17x9 +20 all around with Kumho Ecsta 225/50/R17 all around, and will be going on my 93' coupe on KYB GR2/Eibach sportlines.

the thing is, the tires fit and sit fine in the rear. but the front tires don't clear the strut. so therefor i'm going to get the fronts wrapped in 235/40/17, my question is would that stance look stooopid? or would it look fine

Front: 235/40/17
Rear: 225/50/17
????

Thanks, -jomar

Are you sure that new tire is going to fit?
235 is wider than 225.
I don't know how to calculate the sidewall stuff though.

At any rate, it might look fine.
looks are going to be a personal preference.

The 235 will fit, it will actually fit better because the 225 are stretched.
as far as how tall the tire will be 50 series vs 40 series will it be alright? i'm just wondering, cause i dont want the car to sit like a dragster or something lol.

so....
You had a 225 on there (which was stretched) and it hit the spring, right?
Now you want to put on a 235 (which is wider than 225) and it will fit, right?

nooooo go wit a 225 40 in the front
havin a flush front and stretched rear wont look good trust me i had my rears stretched and the looked sick but i had flush fronts and it looked weird
plus if u go 225 40 in the front it will make it look a lil higher in the back which i like

40 and 50 is a huge difference.

im running 40 in front and 45 in the rear and i can tell big time..

[GunmetalSR]

opps i thought i said 45

use this


Tire size calculator (http://www.miata.net/garage/tirecalc.html)

the only reason they rubbed because they were too tall of a tire.
also, they don't make a 225/40/17 tire. or so my shop tells me

any pics of a car with a 40 series vs 50 series for fr&r?

[Brian]

They DO make 225/40-17, but not many people do.
I think Nitto does.

quick schooling on sidewall

general rule of thumb is that the profile of the tire (35/40/45/50 series and so on) is the percentage of the tread width that makes the height of the sidewall

example: (remember, stated tire widths/series are not actual sizes. just an industry estimate)

Kumho Ecsta 225/50/R17

width of tread of tire = 225mm
sidewall height = 50 or 50% of 225 = 112.5mm / or 40 series is 90mm
tire size = 17" wheel

this is just a tire industry general rule. Refer to the tire mfg site for specifications as every tire from a different mfg in the same size/width class is different...

i had 225/40/17 on my old g35 wheels...bridgestone

i don't think it will look stupid if you have a larger wall tire in the rear. if anything it'll give it a more aggressive look because of the larger looking tire in the rear. it'll give it a sort of stagger look i would think.

for almost a year i had a 50 wall on a 17x7.5 rim up front and a 40 wall on a 17x8 in the rear and it looked kinda silly because you can notice right away.

but if you're more concerned about the width of the 225 and 235, the difference is negligible.

235 on a 9" rim is still kinda stretchy and wouldn't sit flush. i know this because i have a 235 on my 8" rim and it's just BARELY flush.

eventually as i pull in cash or as things sell i will get another pair of 40's to finish the set, i'm talking in terms of driving around town. i just don't want it to look obnoxiously stoopid, like i'm trying to make my car look like a drag car or something like that. as long as its "okay" to the naked eye, then thats fine with me as it will only be temporary

back to the question. It would look a little odd (to an experienced eye) viewing from a rear angle in my opinion.

why not the Kumho Ecsta 225/45/17? On a 7.5" wide rim, the 225/45/17 is .9" shorter than your 225/50/17 according to Kumho site.

how much clearance do you need?

The rims i have are 17x9 +20 all the way around, i have to run the 225/40/17 in the front so it will clear the strut and with that run extended studs and spacers along with pulled/rolled fenders. as soon as i have more money ill be running 225/40/17 in the rear also. so it looks all even
